Use the method of completing the square to transform any quadratic equation in x into an equation of the form (x – p)2 = q that has the same solutions. Derive the quadratic formula from this form. b. Solve quadratic equations by inspection (e.g., for x2 = 49), taking square roots, completing the square, the quadratic formula and factoring, as appropriate to the initial form of the equation. Recognize when the quadratic formula gives complex solutions and write them as a ± bi for real numbers a and b 1 What is the solution set of the equation ? 1) 2) {2,8} 3) 4) 5 The solution of the equation 1) 2) 3) 4) 2 If 1) 2) 3) 4) 6 What is the positive solution of the equation ? , the roots of the equation are and 25 , only and 5 , only is 7 Ryker is given the graph of the function . He wants to find the zeros of the function, but is unable to read them exactly from the graph. 3 A student is asked to solve the equation . The student's solution to the problem starts as A correct next step in the solution of the problem is 1) 2) 3) 4) 4 What is the solution of the equation ? 1) 6, only 2) 2, only 3) 2 and 4) 6 and Find the zeros in simplest radical form.
